Regression analyses
Regression analyses indicated that objective (EASI) and subjective
(POEM) severity of AD similarly predicted sleep quality (PSQI: R²=0.26,
F1,54=18.64, p<0.001; R²=0.24,
F1,55=16.92, p<0.001, respectively) (Figures
3A–B). As shown in Figure 3C–D, the subjective AD severity largely
predicted insomnia symptoms (R²=0.31, F1,55=24.27,
p<0.001) than the objective measure (ISI: R²=0.19,
F1,54=12.26, p<0.001). Therefore, more severe
AD was associated with worse sleep quality and more insomnia symptoms.
